Adolescence is a critical developmental period during which children undergo substantial neurocognitive changes as they transition into adulthood. Because adolescents are impressionable and are beginning to form consumer identities, this population is aggressively targeted by multi-billion dollar marketing campaigns. Continuous exposure to advertisements has been indirectly linked to negative health outcomes such as obesity and substance abuse. However, the precise neurobiological mechanisms underlying this association remain poorly understood. In a series of experiments, I explore how advertisement exposure during adolescence might be more directly linked to negative health outcomes via the brain's reward motivation and learning system. I first demonstrate that some adolescents may be more susceptible to fast food advertisements due to variation in biological risk factors. In Study 1, we observed heightened activity in brain areas associated with reward processing in obese (relative to lean) adolescents passively viewing fast food commercials. In Study 2, we extend these findings to show that children genetically at-risk for obesity demonstrate heightened reward-related responses to food ads in the nucleus accumbens in addition to larger overall volumes of this structure. Although these two studies suggest that susceptibility to advertisements reflects stable differences across individuals, it is also possible that responses to advertisements additionally fluctuate within an individual as a function of dynamically changing goal states, such that common goals might similarly organize how adolescents view ads. In Study 3, we manipulated the goal relevance of alcohol in underage drinkers and find that reward-related responses to social alcohol ads are amplified when they are goal-relevant, and that this relationship is heightened in binge-drinkers. In addition, dynamic response patterns in reward-related brain regions were found to be more consistent across subjects viewing alcohol commercials when they were goal-relevant. Taken together, these results support a biologically plausible framework in which advertisements exploit neurobiological vulnerabilities in adolescent reward circuitry and promote health risk behaviors in youth, which may lead to long-term health consequences in adulthood.
